Specification of Letters Patent.

Application filed April 7. 1908.

Patented Apr 14L, 15nd. Serial No. 425,715.

To (177 whom. i 4' may concern Be it known that we, Anor s'r lVnnnn, Six,

and JOHN Winner; each aritizen of the United States, residing at- Schenectady, county of Schenectady, and State of New York, have invented certain new and use- 't'ulImpi'ovements in Casest'or IncandescentElectric-Lamp Sockets, of which the following is a specification. The invention relates to such improvements and consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings, and the reference characters marked thereon, which form a part of this specification. Similar characters refer to similar parts in the several figures therein.

l igure 1 of the drawings is a central, vertical, longitudinal section of our improved case for incandescent electric lampsockets. Fig. 2 is a top plan view of the shell with the cap removed. Fig. 3 is a bottom plan view of the cap detached. ll ig. t is a view in perspective of a lacked-away portion of the cap. Fig. 5is a view in side elevation of the case complete.

The several figures are drawn on an enlarged scale.

The principal objects of the invention are to provide a more etlicient interlocking mechanism for the cap and shell-members of a case for incandescent electric lampsockets; to facilitate the assembling and interlocking of such parts; and to provide means for preventing relative rotation of said members when applied to each other in any relative rotative position and interlocked.

Other objects of the invention will appear in connection with the following description.

The invention is applicable to the telcscoping members of sheet-metal cases adapted for various uses, and is particularly adapted for use in the cases for incandescent electric lamp-sockets, in which preferred use it is shown in the drawings and hereinafter described.

I. is the shell of the socket preferably 'l'orined oi. sheetanetal, and provided, if for a key socket, with the usual slot, 2, adapted to receive the shaft of the key (not shown).

The. shell is provided near its upper end with a plurality of catches, 4, preferably symmetrically disposed about the periphery of the shell, and projecting outwardly therefrom. For certain purposes of the Invention these catches may be of any desired :t'orm severally adapted to interlock with a seat on the cap.

We have shown as a preferred form of catch one formed by slitting the shell transversely, and outwardly displacing a portion of the body of the shell at the upper side of said slit, thereby forming a downwardly and outardly inclined catch with a cut-metal edge.

One of the catches, 4, is preferably located adjacent to the slot, key-slot or a purpose of rendering the shell compressible. The cap, 3, which is also preferably formed ofshect-1netal is adapted to receive within its lower end the upper end of the shell, and is provided with a continuous seat, 5, extending around its inner periphery adapted to receive and interlock with the several catches, 4, in any relative rotativc position of the shell andlcap. i

The seat, 5, is formed by a ledge or offset, (3, formed by bending an annular portion of the bodyot the cap into a plane perpen dicular to the axis of the cap, making the lower end of the cap substantially "L- shaped in crosssection, said ledge, 6, being adapted to be engaged by tho cut-metal edges of the catches, 4, to lock the cap and shell together to prevent a relative movement of separation thereof.

The lower end, 7, of the cap is adapted to ride over the inclined surfaces of the catches,

at, until the ledge, 6, reaches the lower end of the respective catches, whereupon the parts interlock with a snap action. The cap and shell can' thus be assembled or applied to one another by a simple telescopic movement in any relative rotative position.

By providing the seating end of the cap with the continuous annular ledge, (i, the seating portion of the cap is rendered very rigid and strong, so that the cap is adapted to securely intcrlock with the catches on the shell.

We have shown the cap and shell provided with means for preventing their relative r0- tation when' applied to each other telescopically in any relative relative position, and interlocked by a telescopic movement. Said means comprises one or more projections, S,

2, which may be the slot formed. especially for the innuniber and location that one or more projections, 8, will automatically enter one or morcrespectively of said seats when the shell and cap are a plied telescopically to each other in any re ative rotative position.

This we are able to accomplish by forming saidseats by serratingcertain portions of the upper edge of the shell, whereby a plurality of seats are formed adjacent to each other, and separated from one another by a V shaped tooth or projection on the upper edge of the shell. By thus forming the seats, 10, the seating of a projection, 7, in one of the seats, 10, is automatically accomplished by; a simple relative telescopic movement of the case. and shell, said projection riding down, and being guided to its seat by, the. inclined surface of one or another of .said V-shaped teeth or projections.

What we claim as new and desire to se- :cure by Letters Patent is 1. A device of the class described, comprising a sleeve and a cap having latching mechanism to prevent separation, said sleeve having notches in its end, and said cap having a horizontally ofi'set portion,'and a member bent downwardly from said horizontally offset portion engageable with said notches,

to prevent relative rotation of the cap and sleeve.

2. A device of the class described, com:

bent downwardly from said horizontally oil'- 4 set portion engageable with said notches to prevent relativerotation of the sleeve and cap. 7

In testimony whereof, we have hereunto set'our hands this third day of April, 1908.
